dat_set_consumer_context - set Consumer context
cc [ flag… ] file… –ldat [ library… ] #include <dat/udat.h> DAT_RETURN dat_set_consumer_context ( IN DAT_HANDLE dat_handle, IN DAT_CONTEXT context )
Handle for a DAT Object associated with context.
Consumer context to be stored within the associated dat_handle. The Consumer context is opaque to the uDAPL Provider. NULL represents no context.
The dat_set_consumer_context() function associates a Consumer context with the specified dat_handle. The dat_handle can be one of the following handle types: DAT_IA_HANDLE, DAT_EP_HANDLE, DAT_EVD_HANDLE, DAT_CR_HANDLE, DAT_RSP_HANDLE, DAT_PSP_HANDLE, DAT_PZ_HANDLE, DAT_LMR_HANDLE, DAT_RMR_HANDLE, or DAT_CNO_HANDLE.
Only a single Consumer context is provided for any dat_handle. If there is a previous Consumer context associated with the specified handle, the new context replaces the old one. The Consumer can disassociate the existing context by providing a NULL pointer for the context. The Provider makes no assumptions about the contents of context; no check is made on its value. Furthermore, the Provider makes no attempt to provide any synchronization for access or modification of the context.
The operation was successful.
The context parameter is invalid.
The dat_handle parameter is invalid.
